A pregnancy test performed on the same date as a preventive service may be reported separately using the CPT code appropriate to the test (e.g., 81025, âUrine pregnancy test, by visual color comparison methodsâ) and a diagnosis code from the V72.4X series (pregnancy examination or test).
This process is called continental drift. The plates move because of convection currents in the Earth's mantle. These are driven by the heat produced by the decay of radioactive elements and heat left over from the formation of the Earth.
Tectonic plates move around and can cause earthquakes and volcanic eruptions. First of all, it is important to know that the Earth's crust is broken up into large pieces called tectonic plates. Remember, tectonic plates are giant pieces of the Earth's crust that fit together and move around on the Earth's surface. This movement can be observed and measured using GPS systems, and the edges of the plates can be detected, as their edges can be seen. We also know that these plates move around with respect to one another.
